Physicists may have found a new route into the black hole information paradox

Quantum physics says information cannot be destroyed, but black holes appear to erase it when they evaporate — a contradiction known as the information paradox. Now, researchers have used a mathematical tool called the "double copy" to translate Hawking radiation into particle physics equations, making it far easier to study. Three independent teams reached similar conclusions, suggesting black hole physics may be hidden inside ordinary particle physics math.
